Description

Wire for surgery

The present invention relates to a wire for use in surgery.

Many people in the United States attach great importance to their skin conditions. However, as they age, the rate of collagen loss and fat atrophy accelerates. Skin tissues without collagen support tend to become relatively loose, and at the same time, fat mass will also be affected by the heart Gravity droops, which is a problem that most beauty lovers care about. Therefore, lifting surgery to increase skin firmness is becoming more and more popular.

The traditional lifting operation is to remove the excess and loose skin and then suture the skin tissue again. Although the lifting effect can be effectively achieved, it will cause a larger wound and leave a larger scar. In order to solve this problem, minimally invasive and non-marking thread lifting surgery came into being. The surgical wound is small and can effectively achieve the effect of lifting to improve the problems of skin relaxation and sagging fat.

Buried thread lift operation uses a feather-like wire 9, generally called a feather thread or a barbed thread. As shown in FIG. 1, FIG. 1 is a conventional wire used in the buried thread lift operation. The surface of the wire 9 has a plurality of protruding portions 91 formed by scoring, and the distribution of these protruding portions 91 is the aforementioned feather shape. In the process of the buried thread lifting operation, the wire 9 must first be penetrated into the subcutaneous tissue, and then the wire 9 is pulled upward (that is, pulled in the desired direction). At this time, the protrusion 91 can catch the dermal tissue. , And will pull down the dermal tissue to achieve the effect of lifting.

However, the strength of the protruding portion 91 formed by the score is weak. In the process of pulling, the protruding portion 91 is likely to break and the pulling effect cannot be achieved. In addition, since the nicks are formed through a destructive process such as cutting or etching, the overall structure of the wire 9 is destroyed, the strength and toughness of the wire 9 are reduced, and the wire 9 is broken and easily disintegrated.

In view of the above-mentioned problems, the main object of the present invention is to provide a wire for use in surgery. By disposing a plurality of second wires on a first wire at intervals, the conventional feather-like wire is easily broken and collapsed. Solve the problem.

In order to make your reviewing committee better understand the technical content of the present invention, specific preferred embodiments are described below.

FIG. 2 is a schematic diagram of a first embodiment of a wire for surgical operation according to the present invention. Please refer to FIG. 2. First, the wire 1 of the present embodiment is a wire used in a surgical operation and is applied to a buried wire pulling operation. In this embodiment, the wire 1 includes a first wire body 11 and a plurality of second wire bodies 12. Wherein, the plurality of second line bodies 12 are disposed at intervals on the first line body 11, and the second line bodies 12 and the first line body 11 are staggered with each other. The second line body 12 and the first line body 11 staggered each other in this embodiment means that the first line body 11 and the second line body 12 are non-overlapping and are not parallel. In addition, the second line body 12 includes a second node 121 and two feather-like structures 122, wherein the second node 121 is connected to the first line body 11, and the feather-like structures 122 are respectively located on two sides of the first line body 11.

In other words, the intersection of the first line body 11 and the second line body 12 is the second node 121, and the second line body 12 is fixed to the first line body 11 here to form the second node 121, and the second line The other parts of the body 12 can be dropped on both sides of the first line body 11, so this embodiment is referred to as a feather-like structure 122. That is, the other parts of the second line body 12 other than the second node 121 are the feather-like structures 122. It should be noted that the drawings in this specification only indicate the composition and connection relationship of the first line body 11 and the second line body 12 with lines and dots, and the scope of rights of the present invention may not be limited by the drawings. In addition, a method of fixing the second line body 12 to the first line body 11, that is, a method of forming the second node 121 will be further described later.

The first thread body 11 and the second thread body 12 may be the same wire material, such as a suture used for surgery. Specifically, the first thread body 11 and the second thread body 12 may be a polymer material or a biological material, have the characteristics of toughness and smooth surface, and are biological inertness. In practice, a second line body 12 may be placed on the first line body 11 and the second line body 12 and the first line body 11 are intersected. Preferably, the second line body 12 and the first line body 11 They can be perpendicular to each other, that is, a cross-shaped arrangement as shown in FIG. 2. Next, a second node 121 is formed at the intersection of the first line body 11 and the second line body 12 by contact fusion, compression, or adhesion. In other words, the second node 121 is connected to the first wire body 11 in a manner of contact fusion, compression, bonding, and entanglement, and the portion of the second wire body 12 that is not fixed to the first wire body 11 is the feather structure 122 .

In this embodiment, the second wire body 12 forms the second node 121 in a winding and knotting manner, that is, the second wire body 12 is wound around the first wire body 11 and knotted to form a second wire body. 12. As shown in FIG. 3, FIG. 3 is a schematic diagram of an embodiment of the second node shown in FIG. In detail, firstly, a second thread body 12 is staggered on the first thread body 11, that is, the second thread body 12 is directly passed around the first thread body 11, and then a knot is formed to form a second node. 121. In other words, the second node 121 in this embodiment is a knot, and the second wire body 12 is fixed to the first wire body 11 by the knot (the second node 121). In addition, the knot can be, for example, but not limited to, a single knot, a square knot, a surgical knot, or a trifold knot, preferably a surgical knot or a trifold knot, and FIG. 3 is an example of a trifold knot.

The method of knotting is well known to those skilled in the art to which the present invention belongs, and is only briefly described here. The single knot is easier to loosen. If the second node 121 is a single knot, care must be taken to avoid loosening when knotting. It can also be used in combination with the aforementioned contact fusion, compression, or bonding methods to avoid loosening. The effect of the removal is not limited by the present invention. A square knot is composed of two single knots with opposite directions. For example, the first single knot is forward and the second single knot is reverse. The surgical knot is also composed of two single knots in opposite directions. The difference from the square knot is that the coil of the first single knot is wound twice before the second single knot is played. A triple knot is a single knot with a square knot in the opposite direction. In other words, a triple knot is composed of single knots with the opposite directions. For example, the first single knot is forward, The two single junctions are reverse and the third single junction is forward, as shown in Figure 3.

Then, the foregoing operations are repeated to fix the other second line bodies 12 to the first line body 11 to form a plurality of second nodes 121. It should be noted that the plurality of second line bodies 12 must be disposed at intervals on the first line body 11. Preferably, the distance S2 between two adjacent second nodes 121 can be between 0.5 cm and 1.5 cm, which can be adjusted according to the desired lifting effect or the skin condition applied to the surgical site. For example, for more slack parts, the wires 1 with a smaller distance S2 can be used to achieve a better pulling effect. In this embodiment, the distance S2 between two adjacent second nodes 121 is one centimeter.

In addition, in order to facilitate the formation of the second node 121, a longer second thread body 12 may be taken first, and the length of the second thread body 12 may be trimmed after the knot is knotted or the second node 121 is formed by contact compression. To form a feather-like structure 122 having a proper length. Preferably, the length L of the feathery structure 122 on one side is between 0.1 cm and 1.0 cm, and more preferably between 0.2 and 0.7 cm. The length of the feathery structure 122 in this embodiment is L is an example of 0.5 cm. It should be noted that the length range of the feather structure 122 described herein refers to the length range of the feather structure 122 on one side of the first thread body 11. In other words, after the second node 121 is formed, 0.5 cm is measured from the second node 121 to both sides, and excess portions are trimmed, so that the two sides of the first line body 11 can form a feather-like structure 122 of 0.5 cm.

It should also be noted that the present invention does not limit the length of the first thread body 11 or the number of the second thread bodies 12, and can be adjusted according to the site where the thread lift operation is intended to be performed. The number of the second line bodies 12 and the second nodes 121 in this embodiment is N, where N is an integer of 2 or more, and preferably an integer of 4 or more. If the wire 1 in this embodiment is an embedded wire pulling operation applied to the cheek area, N may be 6. At this time, the length of the first wire body 11 is preferably greater than 45 cm. Specifically, the length of the first line body 11 may be 46 cm, and 20 cm is reserved before and after, and 6 cm is left as a distribution area of the second line body 12. The second line body 12 (and the second line body of this embodiment) The number of nodes 121) is 6, and the distance S2 between two adjacent second nodes 121 is 1 cm. In other embodiments, the wire 1 can also be applied to the chest or other large-scale buried wire lifting operations. At this time, the number (N) of the second wire body 12 and the second node 121 can be 30, and the first wire 30 cm can be left in the middle of the body 11 as the distribution area of the second line body 12, so the length of the first line body 11 can be greater than 70 cm.

FIG. 4A is a schematic diagram of a second embodiment of a wire for surgical operation according to the present invention. Please refer to FIG. 4A. In this embodiment, the first line body 11 includes a plurality of first nodes 111, which are respectively disposed on two opposite sides of the second node 121. In other words, the second node 121 is disposed between two adjacent first nodes 111. If the number of the second line body 12 and the second node 121 is N, the number of the first node 111 is N + 1, so that all the The second nodes 121 are respectively disposed between two adjacent first nodes 111, thereby achieving the effect of limiting.

Specifically, if the second node 121 is a knot, the second node 121 (the knot) may be loosened during the step of pulling the wire 1 upward during the process of the buried wire lifting operation. It happens that the second node 121 is shifted, and even all the second nodes 121 are brought together. The design of the plurality of first nodes 111 on the opposite two sides of the second node 121, even if the second node 121 (knot) is loose, can be limited to the adjacent two first nodes 111 Moving, the first node 111 can achieve the effect of limiting the position, so as to prevent the second node 121 from clustering together due to loosening.

Preferably, the first node 111 may be a knot, which may be, for example, but not limited to, a square knot, a surgical knot, or a trifold knot. In other embodiments, the first node 111 may also be other absorbable The biological material is directly fixed to the first thread body 11 and can also achieve a limiting effect. In addition, the present invention does not limit the distance S1 between two adjacent first nodes 111, which may be equal or unequal. As shown in FIG. 4A, the first nodes 111 in this embodiment are substantially equidistant, so the distance S1 and the distance S2 between two adjacent first nodes 111 are substantially the same, and may be between 0.5 cm and 1.5 cm. It can also be less than 0.5 cm. In this embodiment, 1 cm is used as an example. In practice, a plurality of first nodes 111 having a distance S1 of 1 cm may be formed before the first line body 11, and then a second line body 12 is provided in the middle of two adjacent first nodes 111 to form a second node. 121 is fixed to the first line body 11. At this time, the distance S2 between two adjacent second nodes 121 is also 1 cm.

FIG. 4B is a schematic diagram of another embodiment of the first node shown in FIG. 4A. As shown in FIG. 4B, in this embodiment, if the number of the second line bodies 12 is N, the number of the first nodes 111 is 2N. Similarly, the first node 111 is disposed on two opposite sides of the second node 121, respectively. In this embodiment, the distances S1 and S1 ′ of two adjacent first nodes 111 may be unequal. For example, the distances S1 and S1 ′ are respectively set at 0.4 cm and 0.6 cm intervals, and the second line body 12 may be disposed at The distance S1 is between two first nodes 111 of 0.6 cm. At this time, the distance S2 between the adjacent second line bodies 12 is still 1 cm, and a better limiting effect can be achieved through the first nodes 111 arranged at different intervals.

FIG. 5 is a schematic diagram of a third embodiment of a wire for surgical operation according to the present invention. Please refer to FIG. 5. In this embodiment, the first line body 11 further includes two marks 112a and 112b, which are respectively disposed on two opposite sides of the entirety of the plurality of second line bodies 12, that is, all the second line bodies 12 are located in two Between the marks 112a and 112b, the function of indicating the distribution area of the second line body 12 is achieved. Preferably, the shortest distance SD between the identifiers 112a and 112b and one of the second nodes 121 is between 0.5 cm and 2 cm. The shortest distance SD in this embodiment is 1.5 cm. In other words, the identifiers 112a, 112b of this embodiment are 1 cm away from the closest first node 111 thereof.

In the process of the thread-embedding and lifting operation, the wire 1 needs to be penetrated into the subcutaneous tissue firstly. If the sign 112b appears at the exit end, it means that the second thread body 12 starts after 1.5 cm, so the prompt of the sign 112b Effect, it is possible to avoid the second thread body 12 from passing through the subcutaneous tissue. On the contrary, when the wire 1 is pulled upwards by performing the pull-up step, the mark 112a can be seen at the penetrating end, which also indicates that the second wire body 12 starts after 1.5 cm, so the prompt function of the mark 112a can avoid surgery The practitioner directly pulls the second thread body 12 into the subcutaneous tissue again. In other words, the identifiers 1122a, 112b can achieve the function of indicating the distribution area of the second line body 12.

In addition, the identifier 112 in this embodiment is the same as the first node 111, and both are knots. Therefore, when knotting to form the first node 111, an additional knot can be tied at each end as the identifier 112. In other embodiments, the mark 112 may also be other marks such as a color or a pattern, as long as the indication effect is achieved.

In summary, according to the wire for surgery in the present invention, a plurality of second wire bodies are spaced apart from a first wire body, and the second wire body is connected to the first wire body with a second node and formed on both sides. Feathery structure. The setting of the second node does not destroy the strength of the first wire body, avoids the wire material being easily broken and disintegrated, and the feathery structure is not easy to break due to pulling.
